Reporting and Disclosure Requirements
The FDA now mandates that manufacturers document cybersecurity measures for both premarket and postmarket phases. These requirements apply to all "cyber devices" - defined as devices that include software, can connect to the internet (even unintentionally), and have characteristics that make them vulnerable to cyber threats [4].
Premarket Submission Documentation
Manufacturers seeking FDA authorization through pathways like 510(k), PMA, De Novo, HDE, or PDP must submit detailed cybersecurity documentation as required under Section 524B of the FD&C Act. This requirement has been in effect since March 29, 2023 [3][4]. Key elements of this documentation include:
- Security Risk Management Report: This report, often following AAMI TIR57 standards, evaluates cybersecurity risks separately from general safety risks.
- Machine-readable Software Bill of Materials (SBOM): The SBOM lists all software components and includes safety and security risk assessments for each identified vulnerability [3][4].
The FDA has introduced a shift in focus for risk assessments. Instead of emphasizing the probability of a risk occurring, manufacturers must evaluate exploitability - the likelihood that a vulnerability could be used by an attacker [3]. This approach acknowledges that cyber threats don't follow predictable patterns.
"Cybersecurity is a part of safety and effectiveness" - FDA [3]
To help reviewers understand the broader impact of potential vulnerabilities, the FDA recommends including four specific architecture views in submissions: Global System View, Multi-Patient Harm View, Updateability/Patchability View, and Security Use Case View(s) [3]. These diagrams illustrate how vulnerabilities could affect interconnected systems. Additionally, testing documentation must cover areas such as security requirements, threat mitigation, vulnerability testing, and penetration testing [3].
After receiving market authorization, manufacturers are expected to maintain active postmarket surveillance to address emerging cybersecurity risks.
Postmarket Surveillance Requirements
Once devices are on the market, manufacturers must actively monitor for new and evolving threats. Section 524B requires a Cybersecurity Management Plan, detailing how manufacturers will identify and address vulnerabilities after the device is released [3][4]. This plan must include a Coordinated Vulnerability Disclosure (CVD) process, which outlines how vulnerabilities identified both internally and externally will be managed. It also specifies timelines for developing and releasing security updates and patches [4].
The FDA takes a broad view of internet connectivity, covering devices that use Wi-Fi, cellular networks, Bluetooth, Bluetooth Low Energy (BLE), inductive communications, or even hardware connectors like USB or serial ports [4].
Manufacturers are encouraged to use Vulnerability Exploitability eXchange (VEX) documents to clarify which vulnerabilities listed in the SBOM do not actually affect their device [6]. This helps streamline FDA reviews and allows healthcare facilities to focus on addressing real threats. Additionally, device labeling must clearly state the "Support Life" - the time frame during which security patching will be provided - so hospital IT teams can effectively manage risks [6].
Secure Product Development Framework (SPDF)
The Secure Product Development Framework (SPDF) weaves cybersecurity into every stage of a product's lifecycle. Instead of being an add-on, SPDF integrates security practices directly into both the Quality Management System (QMS) and the Software Development Lifecycle (SDLC) - from initial design to postmarket activities. This approach aligns with the FDA's 2026 guidance on reporting and disclosure requirements [8].
"The SPDF isn't a new, standalone process you bolt onto your existing work. It's an end-to-end discipline that integrates security risk management directly into your Quality Management System (QMS) and software development lifecycle (SDLC)." – Henry Anfang, Firmware Developer, Punch Through
SPDF also aligns with the updated Quality Management System Regulation (QMSR), which incorporates ISO 13485:2016 [7]. The FDA emphasizes SPDF's role in ensuring security is a deliberate and well-managed process throughout the Total Product Lifecycle (TPLC). This systematic approach helps identify and address risks during the entire lifecycle of a medical device.
Core Components of SPDF
SPDF's framework includes several essential elements to address cybersecurity risks across the device lifecycle. At its heart is threat modeling, which relies on tools like Data Flow Diagrams (DFDs) and methodologies such as STRIDE to identify potential risks. This is supported by cybersecurity risk analysis, which connects exploitability assessments (e.g., CVSS scores) with patient safety considerations, following ISO 14971 guidelines.
Security architecture design is another critical component, requiring manufacturers to create a "Security Control Catalog" that lists specific mitigations, such as cryptographic signing for firmware updates. Visual architecture diagrams further illustrate layered defense strategies. The implementation phase involves activities like code reviews, static analysis, and extensive testing to validate these security measures. Additionally, keeping an up-to-date Software Bill of Materials (SBOM) and maintaining a robust vulnerability management process are vital for ensuring ongoing safety after a product is on the market.
Evidence Requirements for SPDF in Submissions
To demonstrate compliance with SPDF, manufacturers must provide specific artifacts in their FDA submissions. These artifacts serve as evidence of how cybersecurity is embedded into each phase of development. A Requirements Traceability Matrix is particularly important, linking identified risks to architectural controls, code implementations, and validation tests. Modern penetration testing has also evolved; testers now use threat models and architecture diagrams to focus on high-risk areas rather than relying solely on traditional "black-box" methods.
| Artifact | Purpose in FDA Submission |
|---|---|
| Threat Model | Identifies threats using structured frameworks like STRIDE |
| Risk Analysis | Connects vulnerabilities to potential patient harm, following ISO 14971 |
| Security Control Catalog | Lists testable security requirements (e.g., "SC-047: Firmware must be signed") |
| Traceability Matrix | Links risks to controls, code, and test cases |
| Penetration Test Report | Assesses device resilience through third-party testing |
| SBOM / VEX | Provides transparency into software components and their vulnerabilities |
| Post-Market Cybersecurity Management Plan | Details processes for monitoring and managing vulnerabilities over time |
These artifacts collectively show a structured approach to managing cybersecurity risks, as required by FDA guidance.
To simplify compliance, manufacturers can automate SBOM generation by integrating tools like Syft into their CI/CD pipelines. Additionally, focusing detailed risk scoring on threats with the potential for Serious, Critical, or Catastrophic outcomes helps balance engineering resources while maintaining safety.
Required Cybersecurity Controls
The FDA's 2026 guidance enforces strict cybersecurity requirements under Section 524B of the FD&C Act, effective as of March 29, 2023. This gives the FDA the authority to reject 510(k) or PMA submissions that fail to include sufficient cybersecurity measures. For manufacturers, these controls are just as crucial as traditional safety standards.
"In today's threat landscape, security isn't optional - it's clinical. The FDA's 2025 guidance makes cybersecurity a central pillar of medical device compliance." – Dr. Mukesh Kumar, Founder & CEO, FDAMap [12]
The guidance broadly categorizes "cyber devices" as any medical devices with software capable of internet connectivity. This includes devices with dormant wireless modules or debug ports. To comply, manufacturers must ensure secure device design and provide thorough documentation, such as a postmarket cybersecurity management plan and a Software Bill of Materials (SBOM) [9].
Mandatory Controls and Practices
In addition to meeting documentation and risk management requirements, manufacturers must implement specific measures to protect the integrity of their devices from cyberattacks:
- Authentication and Access Control: Strictly regulate access to both devices and their related systems, including cloud platforms.
- Encryption: Protect patient health information (PHI) and other sensitive data.
- Integrity Verification: Guarantee secure delivery of software and firmware updates without risk of tampering.
- Audit Logging: Monitor access and identify potential security incidents.
These security measures must be incorporated into the manufacturer's Quality Management System (QMS), which must comply with the FDA's updated alignment with ISO 13485 by February 2026. For devices connected to the cloud, the cybersecurity framework must also cover cloud platforms, mobile applications, and associated data flows [9].
Cybersecurity Testing Requirements
The FDA outlines four key types of cybersecurity testing:
- Security Requirements Testing: Validates that security features are properly implemented and traceable to the design specifications.
- Threat Mitigation Testing: Uses threat models like STRIDE to evaluate and address risks.
- Proactive Vulnerability Hunting: Focuses on identifying potential weaknesses on an ongoing basis.
- Independent Penetration Testing: Engages external experts to simulate real-world attacks [11].
Manufacturers must also conduct vulnerability scanning to identify known flaws, penetration testing to detect and address risks during development, and fuzz testing to reveal software issues by introducing invalid or random inputs [9]. It’s critical to establish traceability between security requirements, design specifications, and test results. Incorporating Static Analysis (SAST) and Software Composition Analysis (SCA) into CI/CD pipelines can help identify vulnerabilities early in development [11].
These testing protocols are essential for integrating SBOMs into device submissions effectively.
Software Bill of Materials (SBOM) and Its Role
As part of the submission process, SBOMs are now a legally required component for all cyber devices under Section 524B(b) [13]. The FDA can reject premarket submissions that fail to include a sufficient SBOM.
"In practice, the SBOM has moved from 'nice-to-have' to essential cybersecurity documentation for medical device submissions." – Viktor Petersson, Compliance Expert, sbomify [10]
SBOMs must be machine-readable and adhere to standards like SPDX or CycloneDX. The FDA uses the NTIA Minimum Elements as a baseline, which includes supplier and component names, version numbers, unique identifiers (e.g., purl/CPE), dependency relationships, author information, and timestamps. Manufacturers are also encouraged to include lifecycle metadata, such as support status and end-of-life (EOL) dates for each component.
To ensure accuracy, SBOMs should not be created manually. Instead, manufacturers should use automated tools that integrate into the build process, capturing the precise state of the software at release. This approach allows SBOMs to function as "living documents", remaining up-to-date throughout the product's lifecycle and directly linked to security architecture and threat models [10].
Postmarket Vulnerability Management and Censinet RiskOps™
Postmarket cybersecurity is becoming more demanding. The FDA’s 2026 guidance emphasizes that managing vulnerabilities is an ongoing responsibility throughout a device's lifecycle - not just a matter of applying patches when issues arise. According to Section 524B of the FD&C Act, manufacturers are now required to implement formal systems for identifying vulnerabilities, communicating with healthcare facilities, tracking security updates, and incorporating security events into their Corrective and Preventive Action (CAPA) systems. These expectations align with existing Quality Management System (QMS) standards and extend to legacy devices as well [1].
This approach broadens the role of cybersecurity in postmarket activities.
"Cybersecurity is no longer a standalone technical consideration - it is embedded into: Risk Management, Design Controls, Validation Activities, [and] Postmarket Surveillance."
– Maven Regulatory Solutions [1]
Vulnerability Assessments and Patch Management
The FDA requires manufacturers to establish clear, documented processes for threat monitoring and patch deployment. This includes continuous vulnerability tracking, automated systems for updates, and structured protocols for disclosing risks. Manufacturers must also include patch management strategies in premarket submissions to ensure a smooth transition to postmarket risk control. Noncompliance with these requirements is considered a prohibited act under Section 301(q) of the FD&C Act [1].
In addition to patch management, manufacturers are expected to adopt coordinated disclosure practices.
Coordinated Disclosure Processes
Under the 2026 guidance, Coordinated Vulnerability Disclosure (CVD) is mandatory. This process ensures manufacturers collaborate with healthcare providers, security researchers, and other stakeholders to responsibly disclose vulnerabilities while minimizing risks to patients. Key elements include timely communication of identified threats, clear timelines for deploying patches, and a collaborative approach to implementing updates without interrupting clinical workflows [2].
These practices pave the way for advanced tools to manage risks more effectively.

Conclusion
The FDA's 2026 guidance sets the stage for a shift in how cybersecurity is integrated into medical device development and management. By embedding security measures within the Quality Management System Regulation (QMSR) and aligning with ISO 13485:2016 standards, the guidance ensures that manufacturers address cybersecurity across the entire product lifecycle - from initial design to eventual obsolescence.
Section 524B of the FD&C Act introduces key mandates for "cyber devices", requiring features like Software Bills of Materials (SBOMs), effective patching mechanisms, and coordinated vulnerability disclosure policies. These measures are designed to tackle real-world threats. A stark reminder of the stakes came in 2020, when a ransomware attack on a German hospital disrupted operations and endangered patient care [5].
"Exploitation of known vulnerabilities or weak cybersecurity controls should be considered reasonably foreseeable failure modes for medical device systems." – U.S. Food and Drug Administration [5]
For healthcare organizations juggling numerous devices across their networks, centralized risk management becomes indispensable. Tools like Censinet RiskOps™ offer a streamlined way to monitor vulnerabilities, enforce vendor compliance, and manage patch updates. By automating workflows and providing real-time risk assessments, these platforms help prioritize vulnerabilities based on their potential impact on patient care while ensuring adherence to postmarket surveillance standards.
This transition to enhanced cybersecurity standards calls for immediate action. Manufacturers must embrace the Secure Product Development Framework (SPDF), establish formal SBOM programs, and embed cybersecurity into their QMS processes. By linking risk management, design validation, and CAPA systems, these steps are critical for safeguarding connected healthcare environments against evolving cyber threats.
